Hi, I have an old Fujitsu Siemens Amilo Pi 1505 laptop - the charger has become very temperamental and I've just noticed the tip of the charger is getting very hot (too hot to touch). What could be causing the problem?
If the charger "tip" is very hot... do you mean the plug that fits in the laptop... then that means there is a poor connection or high resistance somewhere. The current causes a volt drop across the poor connection, volt drop and current flow equals power and that power is heat. At the current a laptop draws it doesn't take much of a volt drop to cause significant heat.
It may be the socket on the laptop that's faulty rather than the plug... one of those things you would have to see really to diagnose correctly... but that's what the basic problem is :)
Another possibility: The constant flexing of the cable at the tip has fractured some of the cable strands. This will cause heating of the remaining strands. If this is the case it will be a simple plug tip replacement.
On advice from a friend I've removed the battery and the laptop works fine. Connection from ac adaptor is better than it was and no overheating. My friend suggests replacing the battery as it appears to be the cause - not cheap but it seems to be the problem.
